(MDPI, 2019-08-01)Regular transmission maintenance is important to keep the infrastructure resilient and reliable. Delays providing on-time maintenance increase the forced outage rate of those assets, causing unexpected changes in the ... -
Coagulation measurement from whole blood using vibrating optical fiber in a disposable cartridge
(SPIE, 2017-11)In clinics, blood coagulation time measurements are performed using mechanical measurements with blood plasma. Such measurements are challenging to do in a lab-on-a-chip (LoC) system using a small volume of whole blood. ... -
Cognitive cooperative MAC with one primary and two secondary users: Achievable rates and optimal power control
(IEEE, 2014-11)We consider a three-user fading cognitive cooperative multiple access channel (MAC) with one primary and two secondary transmitters. We propose two encoding/decoding strategies with varying levels of cooperation, based on ... -
Color filters: When “optimal” is not optimal
(IEEE, 2016)It is well known that many more than three or four spectral measurements are required for accurate measurement of color. Previous work has shown seven to ten measurements can yield accurate results on average, but with ... -
Colour gamut enhancement with remote light conversion mechanism
(IOP Publishing, 2018)The backlight unit spectrum of liquid crystal displays (LCD) directly affects the colour gamut. With the invention of GaN based blue light emitting diodes (LED), phosphors and quantum dots (QD) have gained considerable ... -
